Add satellite names system - Component-based implementation

[wannerdev]

Description

Implements a satellite naming system that assigns codenames to satellites based on their level and spawn order. First satellite of each level gets a fixed codename, and every 10th satellite globally gets a Japanese codename.

Implementation Approach

This is Implementation A - Component-Based approach using spawn statistics tracking and direct label spawning.

Changes

• Created new satellite_names module
• Added SatelliteSpawnStats resource to track spawn counts
• Implemented codename_for_satellite function for name assignment logic
• Added SatelliteLabel component for label entities
• Integrated naming into both start_new_launch and start_launch_from_touch_end
• Labels spawn as child entities positioned below satellites
• Added satellite_names::plugin to main app plugins

Naming Rules

Fixed Codenames (First of Each Level)

• Level 1 (first): "tiny-1"
• Level 2 (first): "traily"
• Level 3 (first): "boinc"

Japanese Codenames (Every 10th Globally)

Every 10th satellite (10, 20, 30, etc.) gets a Japanese codename:

• Sakura, Kitsune, Kumo, Hoshi, Tsuki, Hikari, Yami, Kaze, Mizu, Inazuma, Tora, Ryuu, Kaguya, Akari, Kuro
• Uses romaji (ASCII) for font compatibility
• Cycles through list if more than 15 milestone satellites

Technical Implementation

Spawn Statistics Tracking

pub struct SatelliteSpawnStats {
    pub global_spawn_idx: u64,           // Total satellites spawned
    pub per_level_spawn_idx: HashMap<u32, u32>,  // Count per level
    pub japanese_name_cursor: usize,     // Current Japanese name index
}

Name Assignment Logic

1. Increment global spawn index
2. Increment per-level spawn index
3. Check if first of level → assign fixed codename
4. Else check if 10th globally → assign Japanese codename
5. Else no label

Label Rendering

• Labels are child entities of satellites
• Positioned at (0, -800, 1) relative to satellite
• Font size: 18.0
• Color: White with 90% alpha
• Uses game's retro font
• Automatically follows satellite (parent-child relationship)

Benefits

• Adds personality and identity to satellites
• Helps players track specific satellites
• Milestone celebration every 10 satellites
• Level-specific identity for first satellites
• Easy to reference satellites in gameplay
• Enhances immersion with Japanese theme

Visual Design

• Position: Below satellite (doesn't overlap with fuel/energy labels)
• Size: Smaller than other labels (18pt vs 27pt)
• Color: White with subtle transparency
• Font: Matches game's retro aesthetic
• Readability: Clear against space background

Performance

• Minimal impact: Only spawns labels for named satellites
• Efficient: Uses child entities (automatic transform updates)
• Clean: Labels despawn with satellites automatically
• Scalable: Works with any number of satellites

Testing

• Launch first level 1 satellite → Verify "tiny-1" label appears
• Launch first level 2 satellite → Verify "traily" label appears
• Launch first level 3 satellite → Verify "boinc" label appears
• Launch 10 satellites → Verify 10th gets Japanese name
• Launch 20 satellites → Verify 20th gets different Japanese name
• Check labels follow satellites correctly
• Verify labels don't overlap with other UI elements

Future Enhancements

• Add text outline for better readability
• Implement zoom-based label visibility
• Add fade-in animation for labels
• Support custom player-defined names
• Add label color coding by satellite type
